CVE-2025-67495 is a high-severity cross-site scripting vulnerability in zitadel, published on 9 Dec 2025. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link. ### Official description ZITADEL is an open-source identity infrastructure tool. Versions 4.0.0-rc.1 through 4.7.0 are vulnerable to DOM-Based XSS through the Zitadel V2 logout endpoint. The /logout endpoint insecurely routes to a value that is supplied in the post_logout_redirect GET parameter. As a result, unauthenticated remote attacker can execute malicious JS code on Zitadel users’ browsers. To carry out an attack, multiple user sessions need to be active in the same browser, however, account takeover is mitigated when using Multi-Factor Authentication (MFA) or Passwordless authentication. This issue is fixed in version 4.7.1.

Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies. 2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it. 3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead. 4. Run the tests and summarise what changed and why. 5. If nothing in the project is affected, say so and change nothing.
